AP PSYCHOLOGY

Detailed explanation-1: -The parasympathetic part of your autonomic nervous system balances your sympathetic nervous system. While your sympathetic nervous system controls your body’s “fight or flight” response, your parasympathetic nervous system helps to control your body’s response during times of rest.

Detailed explanation-2: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

Detailed explanation-3: -When the parasympathetic nervous system (PSNS) is activated, it slows our heart and breathing rates, lowers blood pressure and promotes digestion.

Detailed explanation-4: -The parasympathetic nervous system controls processes in the body such as digestion, repair and relaxation. When the parasympathetic nervous system is dominant in the body it conserves energy, slows heart rate, increases digestion and relaxes sphincter muscles in the digestive tract.
